For those who think that I had a botnet, whose composition should be listed here: No, I do not advertise botnet! On the contrary: 
The IP addresses listed here belong to one or more botnets that attack that server here.

Let me take this opportunity to express my regret that anyone may use the Internet without even have to know much about computers. 
* This virus infected computers of private individuals are responsible for 90% of such attacks. 
* The remaining 10% are poor (or not) maintained servers, whose owners own incompetence or laziness excuse the bad hackers. 

For internet as a safer place, we need a "computer driving license"...  ...and this list of offenders ...

Who is on that list, has repeatedly tried to break into this server, as he has started brute force attack on the SSH service. 
He was caught. The server ignores requests from those IPs.

Even if your server is plagued by these demons, use DenyHosts (http://denyhosts.sourceforge.net/) in order to prevent brute-force attacks on SSH. 
With mod_security (http://www.modsecurity.org/), you also protect the Apache from many dangers.

Use this list to protect your server (copy into /etc/hosts.deny). It is created automatically. No guarantee of accuracy and timeliness.
